The Periodic Table Flashcards
Elements that react to form positive ions are…
Metals
Elements that do not form positive ions are…
Non-Metals
What is the name of the Group 0 Elements?
The Noble gases
Noble gases are…
Unreactive and do not form molecules easily because they have stable electron arrangements
All Noble Gases have…
Full outer shells
The Noble Gases consist of…
Helium,Neon,Argon,Krypton,Xenon,Radon,Oganneson
The boiling points of the noble gases…
Increase going down the group as relative atomic mass also increases.
The Elements in group 1 are known as…
Alkali Metals
In group one…
Reactivity increases going down the group.
The Alkali Metals consist of…
Lithium,potassium,sodium
Caesium,rhubidium,francium.
The halogens are…
Non-metals and the molecules consist in pairs of atoms
In Group 7…
the further down the group an element is the higher its relative molecular mass,melting point, and boiling point
In group 7 also
the reactivity of the elements decreases going down the group.
A more reactive halogen can displace a less reactive halogen from an aqueous solution of its salt.
